IMPROVEMENT IN PROCESSES 0F DI'SlNTEGRATlNG MOLTEN SCORIACEOUS SUBSTANCES.

Specification forming part of Letters Patent No. 180,470, dated August 1, 1876; application filed May 15,1876.

To all whom it may co iiccrn Be it known that I, ALEXANDER D. ELBERS,

of Hobokcn, Hudson county, New Jersey, have invented a new and Improved Apparatus for, and Method of, Disintegrating Scoriaceous Substances, of which the following is a specification:

Figures 1, 2, 3, and 4 represent side views of diflerent modifications of my improved ap- )aratus. Fi 5 is an end view of the device such reduction was usually effected on scoriaceous substances by a jet of air or steam propelled through or against a stream of molten sing or scoria; but in practice I have found that, upon striking the flowing mass, the force of the jet of steam or air is spent to a greater or lessdegree, and the reduction consequently not as perfect as it would be. it less changeable power were applied. In the'production of mineral wool a very considerable proportion of objectionable head like globules is therefore produced, simply because the jet of air or stcamdocs not remain sufficiently powerful to follow all the parts of the diffused matter and reduce them in proper manner.

' My invention consists in the use of arotary paddle-wheel, which 1 apply to the molten scoriaceous matter.

Thus a wheel, A, having a suitable number of projecting blades or buckets, a a, at the edge, may be applied, as in Fi 1, beneath the outlet or discharge-opening of a trough or conduit, B, that contains the flowing scoriaceous matter, the wheel being so placed that, in revolving with proper velocity, its blades will strike and diffuse the molten mass, whirling it with considerable force through the air, and causing its disintegration into fibers or other small particles, whose form will, of course, vary according to the nature and composition, and even degree of heat, of the matter acted upon.

The paddle-wheel may be placed at right angles to the outlet of the conduit, as in Figs.2, 4, and 5, to throw the diffused mineral matter in a spray to either one side or the other, as may be desired, and according to where the receiving-chamber may be placed; and it may,

as in Fig. 3, be applied above the conduit with substantially the same efl'cct.

' Heated or-cooled air or steam may be used in connection with my process and apparatus. Thus, in order to prevent the d'iifused particles 0tslowly-solidifying mineral wool from reuniting on contact, they may be thrown into or through a current of cold air, which may assist in further dividing or reducing the particles which fly from the wheel.

By my invention I am enabled to mechanically disintegrate or reduce all molten scoriaccous or equivalent substances into fine fiber, whereby many of these substances will be improved in condition for further use in the arts, and many also brought into useful forms at a comparatively trifling expense.

The trough or conduit B is, of course, combincd with a receptacle, 0, which contains the seoriaceous substances into mineral wool by exposing the same in a fluid state to the action of a rotary paddle-wheel, substantially as herein shown and described.

2. The combination of the rotary paddlewheel A-with the conduit B and receptacle 0, all combined for action on molten scoriaceous substances, vsubstantially as herein shown and described.
